Application led September 13, 1912. Serial No. y.720,187.

T0 all whom it may concern:

Be it known that we, ARTHUR GEORGE Booznn, Jr., and GEORGE HILL, citizens of .the United States, residing, respectively, at Greenville, county of Greenville, and Tucathe State of South Carolina,have invented certain new and useful Improvements in Dofling-Machines, of which the following is-a specication.

This invention relates to doiiing machines arranged to travel along the sides of spinning machines for removing the full bobbins from the spindles and placing empty bobbins thereon.

The machine herein disclosed is of. that type of doifer which comprises two relatively movable carriages,-the one traveling at a constant speed along the spinning frame andthe other carriage, which supports the dofng means, pausing before each spindle being dotted and advancing intermittently the distance between-successive spindles.

One ofv the objects of the invention is to produce a doflin machinev which 'is operable at greater Spee and is more economical of power than, machines heretofore producedA by us.

Another object is to produce means for transferring a doffed bobbin fromthe doffer x spindles.

further object is to produce a mechanism operable when the bobbin is properly dotted to prevent the actuation of the throwout mechanism.y i

The invention also relatesto an improved magazine for empty bobbins and means for feding the empty bobbins to the donning u e.

The-invention further refersfto the general improvement in the' construction and ing a. full bObbll operation of doing machines' witha view to producing a thoroughly eiiicient machine."

In the accompanying drawings, Figure 1 yillustrating s inning machine.

is a side elevation of the upper portionof a doing machine embodying the features of our invention. Fig. 1fL isa view similar to Fig. 1 showing the manner of mounting the magazine for empty bobbins. Fig. 2 is a side elevation of the middle portion of the de fer, the view also showing a part of a spinning frame. Fig. 3 is a side elevation of the lower portion of the dofling machine shown in operative relation to the spinning frame, the view also illustrating a truck which travels along with the doi'er and upon which the doifer is supported when not in association with the spinning machine. Figs.

and 3 are to be readtogether for a complete side view of the doer. sFigs. 3L and 3b aredetail views illustrating the driving motor and a clutch associated therewith. Figs. 4, 5 and 6 together constitute a` front elevation of the doer, the supporting truck not being shown. Fig. 7 is a'horizontal sectional view through the machine taken in the plane of line 7-7 of Fig. 5. Fig. 8 is a horizontal sectional view through the machine taken in the plane of line 8-8 of Fig. 6. Figs. 9 and 10 are fragmentary rear elevations of the lower portion of the toffer, the mechanism in two dierent positions. Fig; l1 is a fragmental sectional detail view illustrating the means for giving the doffer head movement. Fig. 12 is a detail section on line 12-12 of Fig. Y11. Fig. 13 is a-section on linex 13- 13 of Fig. 11. Fig-14: is a top plan view and Fig. 15 a side elevation of the doifer head. Fig. 16 is a detail view of one ofY the ripping ngers comprised in the doi'er head. Figs. 17, 18 and` 19 are respectively plan, rear elevation and sectional views illustratingV the shearing mechanism and a portion of the means for opening and closing the jaws of the doier head. Fig. 20

closing the doer head jaws. Fig. 21 1s a front elevationV ofthe truck for supporting in `association with thel Figs. 22, 22a and 23 are the doffer when not etail views showing the means for receivv from the doer head and discharging` it', into therefor. igs. 24 and 25 illustrate a sensitive mechanism, which is operated twhen the a verticalv reciprocating the receptacle provided,-
